This show is so funny that you could have an episode's joke spoiled for you and still laugh when you see it in the show -- that's what makes Gintama the best anime comedy tbh.
Also he shogun episodes never fail to have me dying laughing at every moment of the show -- it's not even like Sorachi is trying to force the characters to be funny, it just naturally ends up that way. Shogun episodes will never not leave you in pure hysterical laughter and this episode is no exception. The skiing! The "penile brake"! Everything! Even the next episode is wildly hilarious with the bigfoot reference, igloo, being stranded, etc.
